Why does a balloon move in different directions? When we let go of the end, the air rushes out and pushes against the air around the balloon to move it in the opposite direction. The air escaping the balloon (the action) pushes out in every which way and the reaction of the balloon is to […]
What are some short term effects of stress?
What are some short term effects of stress? Short term: You may feel butterflies in your stomach, pain, or nausea, or might even vomit. Your appetite can change and you can have diarrhea, constipation, or heartburn. Long term: Stress can lead to severe chronic pain and changes in your eating habits. You can also develop […]
What is a lowest energy?
What is a lowest energy? These zones are known as energy levels (or sometimes called electron shells). At the lowest energy level, the one closest to the atomic center, there is a single 1s orbital that can hold 2 electrons. At the next energy level, there are four orbitals; a 2s, 2p1, 2p2, and a […]
How is oxygen maintained in the atmosphere?
How is oxygen maintained in the atmosphere? The balance of oxygen and carbondioxide is maintained in the atmosphere by the oxygen released by plants during photosynthesis and carbondioxide released by human,animals etc. in the atmosphere. The balance of oxygen and carbondioxide is made due to respreration and photosinthesis. How did we get oxygen in our […]
Why are fair weather predictions sometimes incorrect?
Why are fair weather predictions sometimes incorrect? Answer Expert Verified 2) The atmosphere always changes with natural disasters occurring such as pollutants in the air that make forecasting difficult. 3) Most of the times meteorologists base their forecasts on probability. Because of differences in the climate, those temperatures are not the same, so errors occur. […]
Which mode transistor is used as amplifier?
Which mode transistor is used as amplifier? common-emitter configuration Which is the largest of the three transistor current? The common emitter amplifier configuration produces the highest current and power gain of all the three bipolar transistor configurations. What is the highest current in any bipolar transistor? The rating for maximum collector-emitter voltage VCE can be […]
What two special image are formed by concave mirror?
What two special image are formed by concave mirror? Concave mirrors can produce both real and virtual images; they can be upright (if virtual) or inverted (if real); they can be behind the mirror (if virtual) or in front of the mirror (if real); they can also be enlarged, reduced, or the same size as […]
How do I calculate simple interest?
How does cyber security affect us?
How does cyber security affect us? Cyber threats are a big deal. Cyber attacks can cause electrical blackouts, failure of military equipment and breaches of national security secrets. They can result in the theft of valuable, sensitive data like medical records. They can disrupt phone and computer networks or paralyze systems, making data unavailable. Is […]
Which way does current flow?
Which way does current flow? The direction of an electric current is by convention the direction in which a positive charge would move. Thus, the current in the external circuit is directed away from the positive terminal and toward the negative terminal of the battery. Electrons would actually move through the wires in the opposite […]
